Renal angiomyolipoma (AML) is a benign tumor. However, rare cases of renal AML demonstrate aggressive behaviors such as tumor thrombus extension into the inferior vena cava (IVC). We successfully treated a case of epithelioid AML in the right kidney involving the IVC. We also reviewed and analyzed 45 case reports of the common type of AML. Radiologists and clinicians should know that epithelioid AML can be an aggressive tumor.

Introduction And Importance: Thymoma is the most common primary anterior mediastinal tumor in adults. Invasive thymomas infiltrate organs adjacent to the mediastinal pleura, including the lungs, great vessels, heart, pericardium, and diaphragm. Complete resection of invasive thymoma leads to a better prognosis.

To explore the value of vessel wall MRI (VW-MRI) in the preoperative assessment of T3 renal-cell carcinoma (RCC) with varying degrees of longitudinal venous system invasion. Patients with RCC with pathological T3 stage between January 2016 and December 2023 were included in this retrospective study. All the patients underwent contrast-enhanced CT (CECT), conventional MRI (con-MRI) or VW-MRI.

Background: Thromboembolic events are a common cause of morbidity and mortality in patients with cancer. While direct-acting oral anticoagulants (DOACs) have been established as the preferred agents of anticoagulation in most patients with cancer, data in resource-limited settings is limited.

Aims: The study aims to assess the comparative efficacy and safety of warfarin and rivaroxaban for cancer-associated thrombosis (CAT) in a resource-limited setting.

Purpose: Comprehension of the anatomical characteristics of pediatric kidney tumors is crucial for making surgical decisions. Previous kidney tumor nephrometry systems failed to incorporate two significant factors: tumor thrombus and multifocality. We develop a refined nephrometry system based on a comprehensive understanding of the characteristics exhibited by pediatric kidney tumors.
